Spicy, sweet foods and hot soups must be avoided by both infants and their nursing mothers. If these prohibitions are strictly observed without violation, the child can be ensured safety and health throughout the illness.
Measles (an acute exanthematous infectious disease) prefers coolness and most abhors warmth. Do not let dry-heat-inducing medicines touch your lips. Misuse will exacerbate the pathogenic fire within, causing toxic qi to stagnate and attack internally, leaving no way to save the patient at that point.
The taste of spicy food and hot soups is often highly favored by those suffering from measles. Why? Because measles belongs to the category of "fire heat" syndromes; fire accumulates internally. Upon encountering spicy and hot substances, the phlegm-fire temporarily finds relief, hence the preference for such foods. Infants with measles must be strictly prohibited from consuming these items to prevent future complications. If one indulges the child's desire for drinks by preparing decoctions of Piper nigrum (Black Pepper) and Evodiae Fructus (Wuzhuyu), or providing strong wine, ginger, garlic, leeks, and Allium tuberosum (Chinese Chives) to satisfy their cravings, although there may be temporary comfort, it will eventually worsen the phlegm-fire. This can lead to the rash turning purple-black, constipation of stool and urine, bloody dysentery, prolapse of the rectum, gingival gangrene, cracking of lips and tongue, rattling of phlegm in the throat, bleeding from the five orifices, unceasing high fever, worsening stomach fire leading to vomiting immediately after eating, and various other ominous signs. For nursing infants, the mother must also observe dietary restrictions. If she fails to do so and consumes spicy foods, any milk consumed by the infant will inevitably lead to unpredictable changes in the condition. Can one afford to be careless?
Since those with measles must avoid spicy foods, physicians treating measles must also be cautious about prescribing pungent, hot, and drying herbs. Herbs such as Cinnamomi Ramulus (Guizhi), Ephedrae Herba (Mahuang), Notopterygii Rhizoma et Radix (Qianghuo), Angelicae Pubescentis Radix (Duhuo), Angelicae Dahuricae Radix (Baizhi), Ligustici Chuanxiong Rhizoma (Chuanxiong), Atractylodis Rhizoma (Cangzhu), Cyperi Rhizoma (Xiangfu), Armeniacae Semen Amarum (Xingren), Atractylodis Macrocephalae Rhizoma (Baizhu), Caryophylli Flos (Dingxiang), Aucklandiae Radix (Muxiang), Amomi Fructus Rotundus (Sharen), Myristicae Semen (Roudoukou), and Cinnamomi Cortex (Rougui) should not be used lightly. If these are mistakenly used during the initial fever stage of measles, they will instead assist the toxicity, causing toxic qi to stagnate and preventing it from venting out, leading to the danger of internal attack. Even if there is coldness of the four limbs at the onset of measles, this is due to "extreme heat resembling water." One must not recklessly administer hot medicines. When the measles naturally erupts, the body temperature becomes moderate. Ancients stated that on extremely cold days, pungent-hot medicines should be used to induce sweating with formulas like Guizhi Tang (Cinnamon Twig Decoction). This demonstrates a lack of understanding: on extremely cold days, it is only appropriate to keep the patient in a warm room and carefully avoid wind and cold. Moreover, even if the weather is extremely cold, the heat-toxin within the human body does not necessarily decrease due to the cold. To hastily use pungent-hot medicines to treat measles because of the cold weather—does this make sense? Quack doctors adhere rigidly to seasonal theories, claiming that extreme cold requires pungent-hot medicines to vent the disease. Consider this analogy: when measles first appears accompanied by vomiting, the doctor, unaware that this is a common symptom, uses Cangzhu (Atractylodis Rhizoma) to calm the stomach, and Dingxiang (Caryophylli Flos) and Sharen (Amomi Fructus Rotundus) to warm the stomach. If there is headache, they use Chuanxiong (Ligustici Chuanxiong Rhizoma), Baizhi (Angelicae Dahuricae Radix), Qianghuo (Notopterygii Rhizoma et Radix), and Duhuo (Angelicae Pubescentis Radix) to treat the headache. If the hands and feet are slightly cold, they immediately use Guizhi (Cinnamomi Ramulus) and Rougui (Cinnamomi Cortex) to warm the extremities. They fail to realize that vomiting in measles syndrome is caused by heat-fire steaming the stomach, and headache is caused by fire-toxin attacking upward. Now, using pungent-warm medicines to attack these symptoms is like carrying firewood to put out a fire. As for the slight coldness of the hands and feet, it is a sign of "extreme heat resembling cold." Once the measles have fully erupted, the hands and feet will naturally become warm. Doctors who do not understand this believe that Guizhi can reach the extremities of the four limbs and Rougui can warm the meridians and restore yang, so they hastily use them. This is an error compounded by another error, trapping patients' lives, which is truly lamentable. Those who insist on using pungent-hot medicines due to cold weather are no different from this scenario. If a patient mistakenly takes pungent-hot medicines, exacerbating the pathogenic fire, resulting in irritability, thirst, and constipation, thereby preventing the measles from erupting, reaching a critical state, the treatment should be Qingyang Tang (Clear Yang Decoction) with Shengma (Cimicifugae Rhizoma), Jiegeng (Platycodonis Radix), and Gancao (Glycyrrhizae Radix et Rhizoma) removed. In my analysis, if pathogenic fire attacks internally, causing thirst and irritability that prevents the measles from erupting, accompanied by constipation, add Heibai Chouniu (Semen Kochiae Album et Rubrum / Black and White Morning Glory Seeds) to purge downward. This embodies the principle of "removing firewood from under the cauldron."
Zhu stated: Hasty use of cold-cooling medicines and misuse of pungent-hot medicines are errors most easily committed by physicians. Generally, when measles is erupting, fever persists. Physicians, aiming to reduce fever, hasty use cold-cooling medicines, which is a major mistake. Furthermore, if physicians do not recognize measles as a heat syndrome and use Xinwen Jiebiao (Pungent-Warm Exterior-Releasing) formulas like Mahuang Fuzi Xixin Tang (Ephedra, Aconite, and Asarum Decoction), it is sufficient to cause mishaps.
